Explanation of how the FEP is treated
Excavation/operation: Neglected since expected effects will occur during Temperate period.
Temperate: Generic modelling of effects on chemistry of fractures and changes of hydraulic conductivity in grouting boreholes.
Periglacial: Not specifically handled. Extrapolation of results from Temperate period.
Glacial: Not specifically handled. Extrapolation of results from Temperate period.
Earthquakes: Not relevant.
